The whole deliverability toolkit
Warmup gets you into the inbox. Placement tests prove it. Monitoring keeps you there. One platform, every plan.
Automated warmup engine
Your mailbox joins a network of real inboxes that exchange natural conversations — opens, replies, and spam-folder rescues that build genuine sender reputation.
- Gradual volume ramp: 5 emails/day on day one, climbing to your target over ~30 days
- Timezone-aware scheduling inside your configured working hours and days
- AI-generated conversation content — no repeating templates for filters to fingerprint
- Automatic spam-folder rescue: recipients move your mail to the inbox and mark it not-spam
- Reply threads with natural delays, capped so conversations end like real ones
- Per-mailbox reply-rate targets and daily volume controls
Inbox placement testing
Send a test to seed addresses across providers and see exactly where it lands — inbox, spam, or promotions — before your real campaign finds out.
- Per-provider placement breakdown (Gmail, Microsoft, Zoho, and more)
- Content analysis flags spam-trigger phrasing before you send
- Track placement over time as warmup builds your reputation
DNS & authentication auditing
One audit checks the records that decide whether providers trust you at all: SPF, DKIM, DMARC, MX, and reverse DNS.
- Clear pass/fail per record with copy-paste fixes
- DMARC policy analysis — know if you're on p=none when you should be enforcing
- Record generator builds correct SPF/DKIM/DMARC values for your domain
Blacklist monitoring
Your domain and IPs are checked against 20 major RBLs (Spamhaus, Barracuda, SpamCop and more), with delisting guidance when something turns up.
- Scheduled scans with alerts on new listings
- Direct delisting links and step-by-step remediation
- History so you can correlate listings with campaigns
AI Copilot
Ask deliverability questions in plain language — the Copilot reads your actual mailbox data, placement results, and DNS state to give specific answers.
- Diagnoses reputation drops using your real metrics
- Explains DNS failures and how to fix them
- Available on every plan, including free
API & webhooks
Pull warmup stats, reputation scores, and placement results into your own dashboards, and get webhook events when things change.
- Read-only REST API with per-workspace API keys (Pro plan)
- Webhooks for warmup, reputation, and blacklist events
